Optimize your cell culture media performance with cQrex® ingredients
LEADING CELL CULTURE MEDIA COMPANIES RELY ON EVONIK FOR THEIR AMINO ACIDS AND PEPTIDES
You may be familiar with our amino acids, specialty carbohydrates, or the plant-based cholesterol PhytoChol®. Our portfolio of cQrex® peptides offers biopharmaceutical companies a wide range of cell culture ingredients manufactured to a consistently high level of quality at trusted, western-based facilities. cQrex® peptides have the versatility to overcome a range of solubility and stability limitations related to specific amino acids. They can also enhance cell culture performance for the production of therapeutic proteins or viral vectors. The cQrex® ingredients are well established for commercial use across the global cell culture industry.
The highest quality amino acids provide you with reliable cell culture media performance
If you are looking for the highest quality cell culture ingredients, you must start with high-quality amino acids. Evonik has been a global leader in the supply of highly pure amino acids for several decades. Here are some of the reasons major media manufacturers and biopharmaceutical companies rely on Evonik as their source of cell culture solutions.
- Our amino acids are non-animal derived and precisely controlled to eliminate impurities including endotoxins and heavy metals.
- As the basis for our cell culture ingredients, our amino acids are fully compliant with cGMP requirements including the use of strict change control policies
- To further reduce regulatory risk, our well-established cGMP manufacturing facilities in Europe and Asia are ISO certified (9001, 14001), and have an excellent inspection record for audits.
Optimized nutrient supply is key to successful cell culture and efficient production of high quality biopharmaceuticals such as therapeutic proteins, vaccines, gene therapies, and cell based therapies. As building blocks of proteins, amino acids are essential culture media ingredients. However, some amino acids have properties that limit their cellular uptake and the bioprocess productivity.
This scientific poster gives you detailled insights about our chemically defined cQrex® peptides, which overcome amino acids limitations and increase performance in biopharma cell culture media.
Cqrex® ingredients ensure quality consistency, reduce risks and improve productivity
Our cQrex® portfolio of peptides is designed to overcome limitations in media formulation and storage stability. Our peptides also help to intensify cell culture processes and drive overall productivity by solving the common stability and solubility challenges of amino acids.
Here are some ways cQrex® can help you improve your cell culture systems.
- To maximize consistency, you can use defined components instead of non-defined complex mixtures to remove a source of risk related to batch-to-batch variation.
- To eliminate the negative effects of excessive salt and pH spikes, you can use soluble peptides that do not require the use of caustic feeds to solubilize sufficient nutrients.
- Our cQrex® peptides help improve titer, boost productivity and get the most out of cell culture processes.
cQrex® ingredients have a long history of use across a variety of commercial biologics programs. They are readily available at commercial scale and manufactured from Western-based facilities.
